The pivot then becomes the fulcrum upon which the lever 78 thereafter moves, so that the stud 82 swings rearwardly, compressing the spring 90. This rearward movement causes the stud to engage the litter-arm 55 and swing this arm rearwardly, thus rocking the presser-toot lever 38 and raising the presser-foot, as shown in Fig. 7.

The construction just described constitutes a convenient means by which a presseri'oot mechanism, organized so as to require two distinct manual operations for the purpose in question, may be modified so that the presser-foot may be released and raised by a single manual operation, and in this aspect the present invention is applicable generally to machines having presser-foot mechanisms so organized. The present in vention is particularly adapted, however, for use in connection with a machine provided with a front-cover which incloses the esser-foot mechanism. In such an arrai gement it is desirable to provide means a ces ible from the outside of the cover for releasing and lifting the presser-foot, so that this may be done without opening the cover. ln t is present instance manually-operable mcans for this purpose are provided, which are supported directly upon the cover in such a position that they may coiiperate with the presser-itoot mechanism normally inclosed \Yltllln the cover. A manually-operable arm 94 is provided with a shank 96 which turns in a bearing in the cover 22, and

is particularly useful in connection with the problem of applying a casing and a frontcover to the specific machine disclosed in said Patent No. 473,870, out it will apparent that various natures of the invention disclosed and c ed h rein applicable to machines at other types, and i 1 1 desci Local draw in combination with sewing-instrumentalities including a-holder, for locking-thread, accessible the front of the machine: a cover, for inclosin forward parts of the machine; and a retainer for said holder united with said cover so as to cooperate with the holder when the cover is in operative position.
